Description

General description

Fenthion oxon sulfoxide is a metabolite of fenthion, obtained by oxidative desulfuration. It is widely used as a pesticide in controlling insects in numerous crops. Its mode of action involves the inhibition of acetylcholinesterase.

Application

Fenthion oxon sulfoxide may be used as a reference standard in the determination of fenthion oxon sulfoxide in water samples using:

• Liquid chromatography coupled with triple quadrupole mass spectrometry (LC–QqQ-MS) and liquid chromatography coupled with hybrid quadrupole time-of-flight mass spectrometry(LC–QTOF-MS).
• High performance liquid chromatography with diode array detection (HPLC-DAD) and atmospheric pressure chemical ionization mass spectrometric detection (HPLC-APCI).
